In 1993, AASHTO published the Quality Control/Quality Assurance Specification and Implementation Guide as a report of the AASHTO Highway Subcommittee on Construction. The Joint Construction Materials task force appointed by the AASHTO Standing Committee on Highways has made significant changes since 1993. We have renamed the publication and printed the Quality Assurance Guide Specification and Implementation Manual for Quality Assurance as two separate, but companion reports.
